ABSTRACT
Objective@#To determine the knowledge, attitudes and practices (KAP) regarding tuberculosis prevention and control among college students in Wuhan, China, while analyzing the factors affecting tuberculosis prevention behavior.@*Methods@#Referring to the National KAP Questionnaire for Tuberculosis Prevention and Control among College Students, which was designed by China Center for Disease Control and Prevention, 22 colleges and universities in Wuhan were selected using a judgment sampling method, and a questionnaire survey was carried out through the online questionnaire platform. The formation of tuberculosis prevention and control behavior among this population was analyzed by single factor and multi factor Logistic regression.@*Results@#The total awareness rate of KAP regarding tuberculosis prevention and control among college students in Wuhan was 79.69%; the awareness rate of core knowledge was 79.28%, and the passing rate was 92.46%. The correct attitude holding rate was 89.69%, while the passing rate was 90.56%. In respect to correct behavior, the formation rate was 72.11%, with a passing rate of 96.62%. The multivariate Logistic regression analysis showed that the following factors were more likely to promote tuberculosis prevention and control behaviors that met the target: female college students ( OR =1.86); college students whose father had a primary school education level, junior high school and equivalent, high school and equivalent, and junior high school students ( OR =2.94, 3.05, 3.17, 3.24 ); no history of tuberculosis ( OR =3.32); the passing knowledge of core knowledge ( OR =9.91), and the passing attitude holding score ( OR =7.35)( P <0.05).@*Conclusion@#The overall awareness rate of KAP regarding tuberculosis prevention and control among college students in Wuhan is acceptable,the mainly influenced factors are gender, history of tuberculosis, awareness rate of core knowledge about prevention and control, attitudes and cognition, and parents educational background.
ABSTRACT
AIM: To compare the effect of small incision extracapsular cataract extraction and phacoemulsification on corneal endothelial cells and explore the differences between these two most commonly used surgeries for grade Ⅱ-Ⅲ lens nucleus. · METHODS: Retrospective study. We retrospectively evaluated the data of age-related cataract patients who had completed surgery in our hospital between June 2013 and December 2015. There were 84 eyes of 84 patients. The corneal endothelial cell density of all the patients were greater than 2000/mm2 and lens nucleus were gradeⅡ- Ⅲ. The patients were divided into manual small incision cataract surgery ( MSICS ) group and phacoemulsification ( Phaco ) group. MSICS group included 42 cases (42 eyes) and Phaco group included 42 cases ( 42 eyes ) . Postoperative evaluations were performed at 1d, 1wk, 1mo and 6mo and included uncorrected visual acuity ( UCVA ) , corneal endothelial cell density and the proportion of hexagonal cells. · RESULTS: There were no statistically significant differences of the two groups in preoperative basic data, UCVA, corneal endothelial cell density and the proportion of hexagonal cells, nuclear classification. The postoperative UCVA were significantly improved in both groups (x2=148. 01, P0. 05). ·CONCLUSION: Manual small incision cataract surgery and phacoemulsification can indiscriminately improve UCVA and decrease the density of corneal endothelial cells. However, the change of hexagonal cells proportion was not obvious. These two surgeries for cataract patients with corneal endothelial cell density greater than 2000/mm2 , grade Ⅱ-Ⅲ lens nucleus have similar efficacy and safety.
ABSTRACT
AIM: To observe the therapeutic effect of combined trabeculectomy with improved conjunctival incision at 1mm of corneoscleral limbus posterior METHODS: A retrospective analysis of 171 cases ( 220 eyes ) with primary glaucoma who were randomly divided into 3 groups according to the differences of conjunctival incision and the way of suture. Group A:44 eyes of 33 cases underwent corneoscleral limbus conjunctival incision; Group B: 94 eyes of 76 cases underwent conjunctival incision at 1mm of corneoscleral limbus posterior; Group C: 82 eyes of 62 cases underwent conjunctival flap running suture based on group B. All cases were followed up for 1a. Intraocular pressure, morphology of filtering bleb, depth of anterior chamber and water leakage in conjunctival incision were observed and compared after operation among three groups. RESULTS: The incidence of postoperative water leakage inconjunctival incision and shallow anterior chamber were group A >group B>group C and there were significant differences among the three groups ( PCONCLUSION: Conjunctival incision at 1mm of corneoscleral limbus posterior and conjunctival flap running suture can not only reduce the rate of water leakage in conjunctival incision and accelerate the speed of incision adhesion after operation, but also significantly enhance the therapeutic effect of combined trabeculectomy.
